Idles high and when driving don't even have to push the gas

Hello, when the engine idles that fast, it's most likely due to air getting to the engine unexpectedly, which is then greeted with more fuel as controlled by the engine's processor. Then the idle speed increases unintentionally. Check for an un-metered air leak into the engine, or a sticking air intake component. Hands on testing is needed to find out what is happening overall with engine performance. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
